Plastic packaging is less able to exclude oxygen from packaged foods than are the older glass and metal containers. Oxygen absorbers collect any oxygen that might diffuse into a food package.<\/p>\n<p>An oxygen absorber is a packet <strong>filled with iron particles and salt that works to retain oxygen<\/strong>. Moisture absorbed by the package combines with iron, salt, and oxygen to rust the iron. This traps the oxygen and usually lets off a small amount of heat. They are used in food packaging to prevent spoiling.<\/p>\n<p>Oxygen absorbers are made in different formulations to match the water activity of the foods they are protecting. The FreshPax Type-D, made by Multisorb Technologies, is designed to be used in dry foods such as nuts and dried grains. The FreshPax Type-B is designed to work with moister foods such as bread and processed meats.<\/p>\n<p>Other technologies are used as well. The Ageless oxygen absorber, as developed by Mitsubishi Gas Chemical, is a sachet of iron (II) carbonate rather than the actual metal powder.<\/p><\/blockquote>\n<p>Interesting&#8230; guess this is a new type of preservative. \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When I was finishing up the Oberto beef jerky the other day, which I had gotten from Costco, I notice one of those preservative packs.
